[Silvio]

Wich command I must use to go out from proxy and then use ftp of Enrico ?

Try to specify the proxy name in the call to InternetOpen():

Code: Select all  Expand view

hInternet = INTERNETOPEN( "Anystring", INTERNET_OPEN_TYPE_PROXY, "your proxy name", 0, 0 )

Please note also the use of INTERNET_OPEN_TYPE_PROXY.

ok but I must insert also mycoduser and mypass for this proxy , and the port number ( my port is 8080)

where i set all this ?

[Enrico Maria Giordano]

I don't think you have to provide them. Anyway, FTP functions doesn't seem to require userid and password of the proxy.
